IPV6....ouch!

IPV6…ouch!

If it wasn’t hard enough to remember IP addresses…. along comes IPV6. Take a look at the differences:

IPV4: 129.146.86.2
IPV6: fe80::aoo:20ff:fea1:6a83

Same address folks, I realize IPV4 addresses are being exhausted, but couldn’t they just add two more octets to the existing structure? IPV6 has not been implemented, yet.

You can check the details out at:

darn it

I agree, that's a highly unfriendly looking IP#. People look at me funny b/c I have mine, the DNS servers, mail server, fav website, etc, memorized. Wonder what they'd think of me then...

[uow!S]

Now the IPv6 address has three conventional forms

The preferred form:

X:X:X:X:X:X:X:X
(x's are the hexadecimal values of the eight 16-bit pieces of the address.)
***********************
use "::"

e.g.
1080:0:0:0:8:800:200c:417e <==> 1080::8:800:200c:417e

***********************
combine IPv4 & IPv6

X:X:X:X:X:X:d.d.d.d

(d's are the decimal values of the four low-order 8-bit pieces of the address in standard IPv6 representation)

So now the example
IPV4
129.146.86.2

can converte to
IPV6
0:0:0:0:0:0:129.146.86.2
or
::129.146.86.2

wow sucks to join counter-strike servers when this comes out..

connect fdfds:234:SDfsadfas;:213.... i think you get the point :\

Gonna need to get a subnet calculator for this.

Decimal Number:
65152::2560:8447:65159:36318
Hex original
fe80::a00:20ff:fe87:8dde

What is the reason for the :: where number set two should be? I did not see it in the article?

And from the article:
The IPv6 protocol solves the pressing problems of IP addressing, while simultaneously making administration easier. It uses an address scheme made up of eight groups of 16 bits, defining a 128-bit network address. This addressing scheme provides roughly 6*10 to the 23rd power addresses per square meter over the entire face of the earth. As a result, it is expected that the IPv6 protocol will last many years into the future.

Why are the examples showing only 6 set of numbers instead of 8? I think with 16 bits and 8 spaces the address should look like this:
fe80:fe80:a00:20ff:fe87:8dde:20ff:45e1

We have the ability to use numbers from 0 to 65535.

Decimal: 65535
Binary: 1111111111111111 (16 ones)
Hex: FFFF

That is a lot of numbers. How acurate is the article with regards to the examples?

The :: means there are all 0(zero).
So the Hex original is
fe80:0000:0000:0000:a00:20ff:fe87:8dde

Can you tell my how to set up the IPv6 protocol, please!
If my ISP doesn't provide IPv6 connection, what else can I do to visit IPv6-based websites?
I heard about "6to4" technology, but I'm not quite sure how to set up. And how it works?_?

thanks~
